Canadian Boating Practice Exam

A fire extinguisher needs to be fully charged in order to be effective in putting out fires. Option A is incorrect because the fire extinguisher should be kept in a dry, easily accessible area, but not necessarily a cool place. Option C is incorrect because shaking it once a year does not have any impact on its effectiveness. Option D is incorrect because practicing with a fire extinguisher can help with proper usage, but it does not affect its effectiveness when actually putting out a fire.
